Stuff like this is why I love this site so much, thanks a lot for posting this.

ok i didn't red thew whole tread but has you q21 experimented other ways to get purer,more concentrated curcumine,i mean.. a method to precipitate it out? maybe naphta or others np solvents and freeze precip or evaporation?maybe acetone could work too..and maybe it could be added of water still curcumine precipitates out of the solution?yeah this is a new iknown area to research!!

ok..here they speack of distillation,acetone seems good

Q21, your a jewel in the crown that is the nexus

I have 1kg of tumeric that i don't use as it just stains teeth too much, now i can put it to use

ok,it seems that oleoresin of curcumin is less volatile than acetone so it will remains as residue on the bottom of where you boil your solvent,so no need of a distillator ---> a new era of burnt hands is starting now! swim hopes to be smart enough to boil it on a bath water far from open flames..he already get burnt one

seems that this oleoresin needs a selective solvent mix to extract the curcumin, swim doesn't think this oleoresin from paint acetone would be foodgrade...he wouldn't eat it

Curcumin, all the rage! If you want to buy curcumin, it is sold as a dietary supplement (anti-inflammatory, and MANY other wonderful healthful effects). It can cost 30 us $ for 60*500mg, sometimes less - check the web, check your grocer!
Also...

The black pepper active piperine potentiates the bio-availability of curcumin by up to 2000%! Please be careful...

I look forward to hearing more and offering my own report as time allows.

Don't know how relevant or interesting this is but here's a patent on how to extract curcumin using soap(?!) and acid. Does anyone know what kind of soap they are talking about here? Where would one find suitable soap without additives that one could use for such an extraction?

Also will try to get some other papers if I can get access to them. the file attached describes the regular process of extracting too, though not in detail.

I'm not clear on the purification process after getting the resin.

Oh and another paper about the ultrasonic-assisted extraction using 70% EtOH @ ph 3 - sounds promising.

thanks enoon!
ljo i searched a bit yesterday at drug stores and others but didn't find E100 that's curcumine,but i didn't specifically ask for curcumin at drugstore,maybe they have it as ''curcumine' antiinfiammatory?

I wonder if one could do a crude extract with ethanol, then redissolve and bomb it with water to purify it... Would this work?

anyway here are some more papers

yeah.. what i was asking myself..imo it's really possible but didn't find anything around saying that,so it seems a bit odd to me

The oil that absorbs into the powder seems likely to be holding on to some of the curcumin, so it doesn't seem like this process would actually concentrate the material all that much. I think I'll just stick to oral administration via delicious Indian food. From the doses described, it sounds like the amounts typically used in cooking are decently active, especially with fresh ground pepper.

Interesting info though. I'd never looked into it, but I always assumed that some Indian spices had psychoactive effects since a large meal of Indian food leaves me feeling pleasantly altered (mild but very clearly noticeable). MAOI effects certainly fit the bill in terms of subjective experience.

Right Enoon, the best looks like making a steam distillation of curcuma longa fresh roots, to gather an essential oil.
This with the piperine crystal in mg's range should give a clear thing.
It's all about distillation these last days ...

Has anyone done any work with raw turmeric root and care to offer some guidelines as to quantities of fresh root compared to dry root?

Is the original bottle holding the oil and tumeric glass or plastic? I have seen tumeric degrade down some plastics (bottle and sandwich bag). Thoughts?

it could be..the curcumin and other stuff into the root are very apolar..just think that curcumin is very soluble in oil, when you cook something the oil turns yellow

I am currently trying this only modified a bit. With my first addition of oil to about 140 grams of tumeric, ALL the oil was absorbed, so I added about 50 ml of oil, and I have been shaking it up and giving it a hot water bath twice a day for 2 days now. I will take it out tomorrow, filtering it all through a coffee filter, and test it on wednesday.

I think i will try tis with organic coconut oil. I found it to be superior with cannabis at getting the good stuff to grab on to the lipids. You can also solidify it to help separation.

Would be promising to add black pepper right to the tumeric extraction in regards of extracting piperine and cucurmin in one step?

I'll also try a butane gas extraction. Just for the fun of it.

This is what I've been doing, as well as increasing bioavailability of the curcumin in the turmeric, the piperine in the pepper has its own beneficial properties. I add the powdered black pepper in with the turmeric powder at the start of the extraction and extract them with the oil together in a warm water bath over several hours.

My current mix is using raw, unprocessed hemp seed oil (preserves nutrients and antioxidant capabilities of the oil), powdered turmeric, black pepper and CBD oil. Need to figure out the best proportions for these ingredients but I think this could be a great mix.

Sounds great Bancopuma! Thank you very much for your input.
